PROPULSION APPARATUS FOR SHIP, AND SHIP HAVING THE SAME

摘要

PURPOSE: A propulsion device and a ship with the same are provided to install a reverse rotating device in the tail end of a hull because the reverse rotating device is composed of multiple bevel gears to reduce the volume thereof. CONSTITUTION: A propulsion device for a ship comprises a rear propeller(20), a front propeller(30), a reverse rotating device(70), a front thrust bearing(52), a rear thrust bearing(53), and a journal bearing(51). The rear propeller is fixed in a driving shaft. The front propeller is rotatably supported in the driving shaft. The reverse rotating device is installed in the tail end of a hull and comprises multiple bevel gears. The front thrust bearing and the rear thrust bearing support thrust load transferred from the front propeller to the driving shaft. The journal bearing is installed in an inner side of a front propeller hub between the front thrust bearing and the rear thrust bearing.
